DISK STOPPER FIOR BOTTLES, &c.

Application led May 22, 1915.

To all whom it may concern.'

Be it known that we, FRANK C. LAUDER- Ma-N and LACICY Y. XVILLIAus, citizens of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Disk Stoppers for Bott-les, &c., of which the following is a specification.

The object of our invention is the provision of an improved disk stopper or cover for milk bottles, jars, etc., which shall be provided with a normally turned down tab at one`edge of the disk, which tab can be raised by the thumb and finger and used to draw the disk from its seat, and which tab also shall be so shaped that. when turned down upon the top surface of the disk an edge thereof will be adapted to frictionally engage the inner surface of the neck of a bottle or jar and additionally aid in holding the disk against displacement, and at the same time itself be retained in its turned down position by such frietional contact.

The invention consists in certain novelties of construction and combination of parts as herein set forth and claimed.

The accompanying drawing shows one main example and two modifications of the embodiment of the. invention constructed according to the best modes of procedure we have so far devised for the purpose.

Figure 1 is a view in perspective of the top end and neck of a, milk bottle or jar with one of our improved disk Stoppers seated and closing the opening to the in terior of the bottle, also showing the tab raised and held by thumb and finger of the hand preparatory to drawing the disk from its seat. Fig. 2 is a vertical cross section in elevation of the bottle neck and disk showing the tab turned down upon the top surface of the disk.A Fig. 3 is a top plan view of the preferred form of the disk as cutl from suitable material and before the tab is turned down. Figs. l and 5 illusf trate disks having tabs which differ slightly in shape from that shown by Fig. 3.

The. tabs are to be cut to shape by dies and from suitable material, such as fibrous paper or composite sheets of specially prepared material, which can be bent and subjected to the required strain without breaking. Paper sheets or sheets of paper with interposed threads or textile of any suitable character may be selected or prepared from which the disks can be eut.

Each of the disks shown by the Figs. 3, Ll and 5, has a curved or circular ed e 1 extending nearly around the same and the edge projects an integral tabjQ, each tab being provided with a curved edge. In Fig. 3 the curved edge of the tab is designated by 3, in Fig. #l by el and in Fig.. 5 the tab has two curved edges 5, 5. The curve of the edge of the tab in each example is an arc of a circle struck from a. radius greater than the radius from which the cir.- cular edge of the disk is struck, inasmuch as it is desirable that the curved edge when the tab is turneddown shall extend or project slightly beyond the -edge of the disk in order that a greater frictional contact of the edge of the tab with the inner surface of thel bottle or jar opening may be secured.

Fig. 3 shows by dotted lines the tab 3 turned down upon the top surface ofthe disk, and it will be noted that when so turned down the curved edge 3 projects slightly beyond the curve defining the body of the disk from the point 6 to the point 7. The curved edges 4 and 5 of the tabs of the other two examples will also slightly project beyond the curved edges of the disks when said tabs are turned down through arcs of degrees upon the top surfaces of the said disks.

The disk is inserted to its seat 8 at the inner surface of the neck of a bottle pref- OID- erably with the tab turned down, though it l may be inserted and the tab turned down thereafter. Such seat 8 generally is made at the lower edge of a slightly outwardly of the curved edge of the 'tab with thel said inclined surface additionally aids in holding the disk itself from accidental displacement.

To remove the disk stopper from its lseat the free end of the turned down tab is grasped by the thumb and finger and raised as shown by Fig. 1; and a slight pull will draw the edgeof the disk adjacent the tab e from its frictional contact with the seat and the loosened disk can then bodily be removed.

From the foregoing description taken in connection with the drawing 1t will be seen i that we here produced en improved disk idr/.2,027

2. A `circular shaped disk stopper of suitable material having a tab With a curved edge struck from a greater radius than the radius from which the circular edge yof the disk is struck, whereby when the tab is in a plane parallel withy the disk the said Curved edge of the tel) will project slightlj eylond the adjacent circuler edge of the is i.

In. testimony whereof We eHiX our signatures.
